Follow-up results of the beta autoradiography, microradiography and ceramography of the BR2-P11 irradiation experiment

Automatic translation: In this report, the results of the follow-up investigation of the loading from BR2-P11 are presented and discussed. The aim of BR2-P11 was to confirm the statement of the Prados-Scott model in a geometry test and to quantify model in a geometry test and to quantitatively determine that in the case of BISO incubation particles, increasing the buffer layer thickness increases the life expectancy. increases the life expectancy. At an irradiation temperature of about 1200°C fast fluences of 8x10'2'1 (E> 0.1 MeV) and burn-ups of 13 % fima were achieved (enrichment of the nuclei: 9.5 %). Particles with 40μm buffer layer had a damage rate of 25 %. The particles with 80μm and 160μm buffer layer were without defects. defects. A comparison of the R/B values with the damage rates found makes a strong temperature dependence of the R/B values probable. The lower capsule of a pug B rig has a strong axial loading has a strong axial temperature drop.
